WOOD-SAWlNG MACHINE...

SPECIFICATION forming part of Letters Patent No. 777,678, dated December 20, 1904.

Application filed May 25, 1904:, Serial No. 209,751.

have invented a new and useful VVood-Sawing' Machine, of which the following is a speciiication.

Th s inventlon relates to wood-sawing machines; and it has for its object to provide a device of this class which shall be especially adapted for the purpose of sawing cord-wood, poles, slabs, and the like into proper size for fuel.

A further object is to provide a machine of this class with elevating means, whereby the wood as it drops from the saw is received and conveyed to a place ofdeposit.

With these and other ends in view, which will readily appear as the nature of theinvention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being understood, however, that no limitation is necessarily made to the precise structural details therein shown, butthat the right is reserved to any changes, alterations, and modifications which come fairly within the scope of the invention and which may be resorted to without departing from the spirit or sacrificing the advantages of the same.

In said drawings, Figure 1 is atop plan view of a wood-sawing machine constructed in accordance with the principles of the invention and showing the same connected with the main axle of a traction-engine from which motive power is derived. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view, on an enlarged scale, taken on the line 3 3 in Fig. 1. Fig. 1 is a side elevation of the machine with the elevator detached and placed thereon in condition for moving. Fig. 5 is a detail view representing a clip which is used in connection with my inventlon for the purpose of connecting the front axle of the machine with a draft-tongue or with the front axle of a traction-engine, as the case may be. Fig. 6 is a cross-sectional view of the elevator. Fig. 7 is a detail view in elevation of the front truck of the machine. Fig. 8 is a detail plan view of the front axle of the machine, showing the hounds which when the machine is in operative position are used for connecting the same with the front axle of a traction-engine. Figs. 9 and 10 are detail views illustrating slight modifications. Fig. 11 is a detail plan view of a portion of the machine including the traveling table, showing the same partly withdrawn from the saw.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The frame of the improved machine includes side beams 1 2, a front cross-piece 3, and a pair of spaced rear end pieces 4 and 5, said frame being supported upon the front and rear axles 6 and 7, having the transportingwheels 8. -The side sills of the frame are provided with bearings 9 for the arbor 10, carrying the saw 11, which latter is an ordinary circular saw. Said arbor also carries a flywheel 12 and a pulley 13, which is connected, by means of a belt 14, with the source of power.

15 designates a counter-shaft, which is journaled in bearings 16 upon the sill and which carries a pulley 17, driven by means of a belt 18 from a small pulley 19 upon the saw-arbor. The counter-shaft 15 carries a sprocket-wheel 20, which is connected, by means of a chain 21, with a sprocket-wheel 22 upon a shaft 23, which latter has its bearings in boXings 24 upon a pair of inclined braces 25, the upper ends of which are connected with the under sides of the sills and the lower ends of which are connected by brace-rods 526 with the sills, struts 27 being interposed between the lower ends of the brace-beams of the sills, there by forming trusses which operate to reinforce the sills of the machine and which at the same time form solid bearings for the shaft 23. The latter supports the pivotal] y-moun ted lower end of an elevatorasing 28, which consists of a trough having flaring or inclined sides 29. Suitably connected with the lower end of said elevator trough or casing is a hopper 30, preferably constructed of sheet-steel and having flaring sides and rear wall which are disposed in close proximity to the sawarbor in order that the pieces of wood dropping from the saw will gravitate into said hopper.

The back wall 31 of the hopper 30 is provided with an opening 32, over which a door or valve 33 is suspended upon a transverse stem or hinge-rod 34, said valve or door being held normally in a closed position by gravity.

The shaft 23 carries adjacent to the elevator-casing a sprocket-wheel 35, which is connected by a chain 36 with a sprocket-wheel 37 upon a shaft 38, which is supported in suitable bearings near the upper end of the elevator-casing. The shaft 38 carries between the walls of the casing a pair of fixed sprocket-wheels 39, supporting the upper ends of the elevator-chains 40, the lower ends of which are supported by means of sprocketwheels 41, which run idly upon the shaft 23 between the side walls of the casing. The chains 40 are connected at suitable intervals by means of transverse slats 42, which cooperate with the chains toform an endless carrier, whereby the wood may be conveyed away from the saw and to a point of deposit above which the discharge end of the elevator is disposed.

It will be observed that while the upper lead of the endless carrier travels upon the support afforded by the floor of the elevatorcasing the lower lead is suspended below said floor and that when the slats 44 reach the lower limit of their movement and are again carried upward by the sprocketwheels 41 they will push aside and displace the door or valve 33, passing freely under the latter. At the same time wood falling from the saw into the hopper will be prevented by said door or valve from dropping into the opening 32 and by any mischance becoming stuck there to the possible injury of the machine, or at least involving the temporary stoppage of the same.

Between the rear cross-bars 4 and 5 of the frame of the machine are supported a pair of uprights 45, which may be suitably braced and sustained in an upright position. These uprights are provided upon their rear sides with ratchet-bars 46, the teeth of which are somewhat hooked, as represented, and adapted to support a vertically-adjustable cross-bar 47, which is adapted to support the trough of the elevator at any desired inclination, one of the uprights 45 being disposed at each side of the carrier-trough.

The frame of the machine is provided with guides 48, supporting an ordinary longitudinally-reciprocatingsaw-table 49, which is provided with rotary supporting means, such as wheels 50. The lower half of the saw is protected by means of a casing 51, supported from the under side of the guides 48. A similar protective casing 51 is attached to the sliding saw-table, said casing being open at its end for the passage of the saw and adapted to move with the saw-table so as not to interfere with the action of the saw, but to act as a protection for the operator and for persons standing close to the machine.

In Fig. 4 of the drawings has been shown dotted lines indicating a log supported upon the saw-table in position to be operated upon, the movement of the saw-table being indicated by an arrow. It will be readily understood that when the saw-table is moved in said direction the material will be operated upon by the saw, the casing 51 meanwhile receding from the saw, together with the saw-table. hen the latter is at rest, the casing 51 protects the saw and constitutes a guard, as will be readily understood.

In Fig. 5 of the drawings has been shown a representation of a clip which is connected with the front axle of the machine for the attachment to the latter of means whereby the same may be connected either with a draftpole or with the front axle of a traction-engine, whereby it is to be operated. This clip is made from a single flat plate of sheet metal of suitable thickness, and the rear edge is turned down so as to form a flange 53, abutting upon the rear side of the axle. The top member of the clip, designated 54 and which has the downturned flange 53, is provided with a central perforation 55 for the passage of a king-bolt and with openings 56 for the passage of bolts, whereby it may be securely connected with the axle. Said body-plate 54 has a forward extension 57, provided with downturned side flanges 58, the rear edges of which will bear against the front side of the axle and which are provided with perforations 59 for the passage of a bolt by means of which a tongue 60 may be secured between said flanges. The clip 54, which may be described as constituting a fifth-wheel, supports a rocker or bolster 70, at the ends of which are mounted blocks 71, supporting the frame sides 1 and 2, which are connected with said blocks and bolster by means of bolts 72.

61 61 designate a pair of links or braces, each of which is provided at one end with a hook member 62 and at its opposite side with a connecting-plate 63, having an obliquelydisposed perforated extension 64. The front axle of the machine is provided intermediate the clip-plate and the supporting-wheels with eyebolts 66.

hen the machine is ready for transportation, the tongue 60 is mounted between the flanges 58 of the clip-plate and the hook members 62 of the braces 61 are placed in engagement with the eyebolts 66, while the obliquelydisposed extensions 64 of the plates 63 arep'laced in engagement with the opposite sidesof the tongue and are connected therewith by means of a single connecting-bolt 67. The brace members 61 thus constitute a pair of hounds whereby the tongue is securely connected with the front axle of the machine in such a manner as to permit the necessary upand-down play, while lateral movement of the tongue with relation to the front axle is prevented. VVhen the machine is to be connected with the traction-engine for operation, the bolt 67 is detached and the ends of the braces 61 having the oblique extensions 64: are placed in engagement with perforated brackets 64 upon the front axle 65 of the traction-engine. Owing to this method of connecting the machine with the engine, the machine maybe moved from one position into another, so as to follow up the work without necessity for detaching and resetting the same.

The operation and advantages of this device will be readily understood from the foregoing description, taken in connection with the drawings thereto annexed. The machine is primarily devised for the purpose of sawing stove-wood either from poles, limbs, cordwood, slabs, or the like. Machines of this kind have been commonly used for a long time and have been driven by steam or other power, it being well recognized that a great amount of labor may be saved by cutting stovewood in this way by machinery instead of manually.

By this invention the labor of carrying the Wood away from the saw may be dispensed with, inasmuch as by properly setting the elevator the Wood will be carried away to any desired distance from the machine as fast as it is being sawed, and the disagreeable, arduous, and dangerous work of removing the stove-wood from the machine as it isbeing cut is entirely done away with.

The machine, as will be seen, is extremely simple, and when attached to and operated by a traction-engine it may be readily shifted from time to time, so as to follow up the work, according to the disposition of material that is to be cut into stove-wood or to the location of the pile of wood that is being cut, or both. It is obvious, however, that the improved machine may be driven otherwise than by a traction-engine-thus, for instance, by horsepower, by a gasolene-motor, by an ordinary engine, or in any approved manner. An ordinary threshermans traction-engine is, however, especially named in connection with my invention as constituting a convenient operating means for the reason that it may thus be successfully employed at times when otherwise it would be idle.

As will be seen by reference to Fig. 7 of the drawings, I prefer to mount upon the front axle of the machine a rocking bolster 2, between which and the sides of the frame proper are interposed spacing'-l.)locks 3, whereby the front wheels of the truck are enabled to turn under the frame of the machine, thereby enabling the latter to be turned in a short space.

In Fi 9 has been illustrated a modified and generally preferred construction which relates to the disposition of the elevator or enclless carrier with regard to the frame of the machine. In the several figures the boxes 24-, supporting the lower end of the elevator, have been shown as mounted upon the lower ends of the braces 25. Under the modified and usually preferred construction illustrated in Fig. 9 the boxes 24:, supporting the lower elevator-shaft, have been disposed upon the under sides of the braces 25. This construction and arrangement of parts is preferable for the reason that by simply removing the halfboxes the shaft may be detached from its bearings, and the machine may thus be more readily and conveniently folded for transportation.

1 also in Fig. 10 of the drawings illustrate a slightly-modified construction of the elevator, whereby the slatcarrying chains have been set in a short distance from the edges of the elevator-trough, necessitating a corresponding location of the sprocket wheels which carry said chains. This construction will be found preferable in order to enable the elevator-trough to be more conveniently mounted in position for operation.

Having thus described my invention, What is claimed is- 1. In a machine for sawing stove-wood, a portable frame mounted upon transporting wheels, a saw-carrying arbor, an elevator includingan endless carrier and atrough mounted hingedly to receive the discharge from the saw, a guide-frame, a movable saw-table supported upon the latter, and a sawcasing mounted upon the movable saw-table, said casing being open at one end for the passage of the saw.

2. In a machine of the class described, a

frame including longitudinal sills, a saw-carrying arbor mounted upon said sills, downwardly-inclined braces and truss-rods connected with each other and with said sills, struts interposed between the braces and the sills, a shaft mounted upon said braces in proximity to the saw, and an elevator including a trough hingedly connected with said shaft, and an endless carrier engaging sprocketwheels mounted loosely upon said shaft and driven by a sprocket-wheel fixed upon said shaft and connected by a chain with sprocketwhcels upon a shaft supporting the outer end of the carrier.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
